AMHERST – Carol Hepburn, the town's animal welfare officer was on her way to the Crocker Farm Elementary School to talk to children about the dog that bit two students Thursday afternoon, the first day of school.

According to a letter sent home by principal Derek Shea, fourth and fifth grade students were playing in the large playground when "an unleashed dog appeared and bit two of our students. An adult arrived on the playground and took hold of the dog. The individual and the dog quickly left the school grounds.

"Our school nurse assisted the two students who were bit and their families were contacted right away. The police were called and they actively tried to make contact with the dog owner. Other 4th and 5th grade students were supported as needed after having witnessed the event that caused concern for them.

"Please let us know if your child would benefit from additional support after this unfortunate event."

Hepburn, who works with the police department, had been on vacation but returned Friday to investigate. She said they were trying to locate the dog.
